Yes.

FYI, the "eļectrum.org" is the ASCII version of punycode: "xn--eectrum-9hb.org" <--- Warning: phishing site.
It will be displayed as the latter if you're using Firefox with show_punycode enabled.

Try to type the original url on the right box here: https://www.punycoder.com/ then press "<<Convert to text" and it will be displayed as eļectrum.org.

From the same thread linked in BitMaxz' post: Re: Fee estimation failed. Fallbackfee is disabled....
You need to open bitcoin-qt or bitcoind, not bitcoin core gui's console.
T/N: If you set it to 0.0002, it will set the tx fee to 20sat/byte if the fee estimation still failed.

Or as the error said, "wait a few blocks" as your node must be a few blocks away.

I know there's a video of the developers explaining their LN implementation on Youtube...
AFAIK, there's indeed an optional 3rd-party server to handle LN transactions and to enable you to receive through your channel(s) even though your client is offline.

I will try to find it, I'll just edit this later.
Ehm, I can't tell which one is it, just pick one from google search: Google Search: electrum "lightning network" youtube  

You mean "vcredist"?
It should be named as "Microsoft Visual C++ (year) Redistributable" in the "Add or Remove Program" and not as the downloaded file's name.
But this file wasn't mentioned in the pre-requisites and somehow not related to the miner, just Microsoft .Net Framework  

BTW, the last commit was 29 June 2018, this was pretty much abandoned.

Just remember that "that" example 600 required confirmations for VET is only limited/required to the exchange, merchant or any 3rd-party services.
In their (Digital Currencies) Blockchains' protocol, one confirmation is as good as "sent".

As for 51% attack, you might need to read more about "mining" to understand the written articles about it on the internet.

Basically, a malicious Pool/Miner who controls more than half (51%+) of the total hashrate (mining power) of the network could alter the newest block(s) in a variety of ways, the deeper the block, the harder it is to make an alteration (but even the latest block isn't an easy feat).
That's why merchants/exchanges want their transaction(s) buried in the blockchain as deep as possible.

To give you a quick look at the average reward after "that" happened, you can just look at the current blocks' coinbase transaction's output and deduct the "Block Reward" from it.

For example:
Block #583560 has this coinbase transaction: a1a57bb8a361bf6c59275eef61d02185c1769ba99e936679105e022f0c9fa11e with an output amount of 13.21486332 BTC.
Deduct the current block reward from it which is 12.5BTC.
The miner's "Transaction fee earning" is 0.71486332BTC.

By that time, we hope that the value of BTC become phenomenal or else.... the total network hashrate might plummet, thus the Blockchain's security against 51% attack.

Are you seriously considering that 0.5% less dev fee version of Claymore miner in exchange for a possible security risk?
That's not open-source and the developer had never shared the code (he just explained it here | & here) but still, it's already compiled.

Anyways, check what's set in the bat file.
My two cents is your address might be missing 1 character (42 characters including the 0x), that's why claymore is adding 0 after the "0x".
You have to stop the miner before changing the address though.

Earlier models, yes.
But I'm sure that the latest (Oculus Rift S) uses LCD display not because of the radiation issues (or they didn't want to disclose it) but for the reduced screen-door effect.

So, it's for verification then? Android version can't do that.

You can just create a "watch-only single address wallet" in your PC and create the unsigned raw transaction,
then import it to your cold storage Android Phone for signing.
If you don't have a PC, you can ask someone to create the raw Tx for you as they will only need that change address and the recipient's address.

Or is this an implicit feature request for Android version?

A small correction to your example scenario: It will be based on the number of unspent outputs (UTXO) from your "inbound transactions" not from the number of addresses alone (as they said: there's no addresses in the protocol level).
If you've used an address to receive BTC multiple times, it will have multiple UTXO and that address will display multiple times in the "send-all transaction" as inputs.

-already answered-

In terms of longevity, use a server PSU as much as possible because it was built to run 24/7.

Using multiple ATX PSUs will work but most of those have less efficiency than server PSU even with 80+ Gold standard rating.
But in terms of efficiency, the percentage is always the same whether you're using one or more PSUs and in the end, it will be based on the total efficiency rating.

Example: a 1000W ATX PSU with 80% efficiency could waste 20% (200W) of the energy into heat and to reach 2000W by using two, they could waste double (400W).
In comparison, a 2000W server PSU with 80% efficiency could also waste the same 400W of power.

There is one big problem with this: Bitpay's agent or Bitpay's server doesn't have an access to your private keys for them to send your funds to another wallet for you.
Plus, your screenshot's recent transaction's timestap is kinda weird (the upper-most received transaction's date is June19).

This is a big red flag IMO.
Where did you downloaded the wallet or what email/customer service have you contacted?

The last sentence of my post comes with a link to Bitpay's support page with step-by-step guide on how to get the xprv key to be able to import the private keys to another wallet with import master private key option (ex. Electrum), just choose from option 1 or 2.

If Bitpay's "12-word passphrase backup" is BIP39 SEED, you can directly import it to any wallet that supports BIP39 SEED to be able to spend that address' missing balance.

Use it as the last resort; for now, focus on restoring the balance of your Bitpay wallet natively.

Clearing the cache didn't worked, have you tried to let it open for a couple of minutes? (in case of internet connection issues)

---

-Update-
The output was now spent, I guess clearing the cache had solved the issue?

From the looks of it, these set of transactions weren't the issue.
Tx1 was spent from the change of Tx2 which completely spend your 0.0363btc deposit.

The issue is the other "recus" in history with a value of 0.0296BTC that was missing in the total balance.

You can check the transaction ID yourself by pasting it in the search box in the links on your quoted post above.
If the balance is still there "unspent" (green), the issue must be on the wallet's cache like BitMaxz said.
If it was "spent" (red), it must be something else.

Looks like this is the 0.0296BTC deposit's transaction ID: 0c3ead295d2a69fceeca756735b5ee0721482bdef8f5c438e78d5f7d56b94c60.
If it is, it's Bitpay wallet's issue because it is still unspent.
Don't worry, you can always recover the private key(s) including the funded address if things gone wrong.

Ping: 3381ms to 14024ms, that's one serious latency issue.

The "network" consists of all the nodes, each have a copy of the full (or partial) "blockchain" which is a chain of blocks where the UTXO (unspent outputs) are "recorded".

So, having a copy of the blockchain, every transaction that they will (usually automatically) save to their own mempool and relay to other nodes should have a valid UTXO, signature, specific preferences, etc. or else, it will be rejected and wont reach other/mining nodes.

Hope you get this.

Meh, the only working free/paid accelerator online that I know is viaBTC, others are fakes or rebroadcaster marketed as accelerator.

Your examples:
∙ bitaccelerate isn't an accelerator, they unintentionally self-confessed that they are using the term "accelerate" incorrectly through this message on their page:
∙ confirmtx is probably a scam and their thread has been receiving a lot of warnings and bad experiences from users.

You probably want to tell him the do's and don'ts on the private key, also what to do after retrieving it 

Newbies have a tendency to mishandle sensitive data if not instructed well.

Can you share what you've typed in the "user URL" (excluding the username/password)?
Make sure to read your selected pool's proper command for cgminer, it may be different depending on the pool.

Something like this:
Also, this should be moved to Mining (Altcoin).

You need to at least become a Jr Member to be able to attach screenshots/images to posts.

Just try to enclose them inside [img][/img] tag now and it will be posted as links.
The images will be displayed after ranking up (30 activity & 1 merit); or buy a copper membership to lift your newbie restrictions.
